new and useful Improvements in Closuresfor Bottles, Jars, and other. Receptacles, of which the following" is a specification.

The invention relates to improvements in closures for bottles, jars and other recep-v tacles; and it consists in the novel features, structure and combinations of parts hereinafter described, and particularly pointed out in the claim.

The inventioncomprises a cap to be ap plied over the mouth of a bottle, jar or other receptacle and having in its lower-edges an annular outwardly projecting recess to receive a packing-ring preferably in line with an annular shoulder formed on the bottle neck, and a split removable locking ring adapted to be brought into engagement with the lower surface of said packing-ring and the upper surface of the annularly projecting recessed portion of the cap and compressed vertically, whereby it is securely though detachably held around the lower edges of sald' cap, and a portion of said acking ring is squeezed laterally against tie bottle neck, the cap being thus securely locked u on the bottle neck and the latter sealed t ereby. The locking ringis of special construction in that its ends overlap each other and the upper portion of one end is formed wlth a tongue and the upper portion of the other end with a recess, whereby when the ends of the locking ring are in position about the lower edges of the cap and the upper circumferential portions of said ring are com. pressed downwardlyupon the upper surface of the recessed portlon of the cap, the tongue on one end of the ring will lie within the recess formed in the other end thereof and serve as means to prevent the ring from expanding and losing its position withthe cap. The cap proper is not of novel structure but is shown in Letters Patent No. 795,283 granted to me on July. 25, 1905,'which patent also shows the locking ring of this application less the novel features thereof made the subject of the present claim, these features relatin to the overlapping end portions of the loc ing ring and the 1nterlock ing tongue and recess formations thereof.

The invention will be fully understoodfrom the detailed description hereinafter presented, reference being had to the accompanylng drawings, in which;

Figure 1 is a top view of the up er por-.

tion of a jar equipped with and sea ed by a closure constructed in accordance with and embodying my invention ,Fig. 2 is a central vertical section of the same on the dotted line 2-2 of Fig. 1; Fig. 3 is a detached elevation, partly brokenaway, of a blank from which the locking ring of the closure may beformed; Fig. 4L is a detached perspective view showing the locking'ring prior to the final bending inwardly of its upper c1'rcu1n-' ferential portion; Fig. 5 is an enlarged vertical transverse section through a portion of due edge of the jar having the closure ap-' plied thereon, the parts of the closure being shown in their initial condition and relation to each other prior to the application of vertical pressure by which the two members of the closure become firmly bound together;

In the drawings, 15 designates the closure as a Whole, and 16 the neck of a bottle, jar,

or other receptacle, having an exterior annular shoulder 17 at a suitable distance below its upper edge;

I The closure 15 comprises the cap 18, packin ring 19, and split locking ring 20, the pac ring 19 being of rubber or other. suitable yielding material and the ca 18 and split ring 20 being of tin, aluminum, or other suitable material. The cap 18 has side walls 21 adapted to pass freely downward upon the exterior surfaces of the bottle neck, and at the lower edges ofsaid sides21 the metal of the cap is flanged outwardly, as at 22, and downwardly as at 23,

. whereby an annular outwardly projecting packingring 19, the latter, as shown in Fig.

5, being initially greater in vertical depth than the depth of said'recess and in horizontal thickness being about equal to the width, laterally considered, of saidrecess, whereby the inner walls of the packing ring are adapted to pass downwardly over the bottle neckto about the position shown in .Fig. 5, in which it will be observed that the horizontal center of the packing ring is about in line with the shoulder 17fon the bottle neck, a part of said packing ring being disposed above said shoulder and a portion thereof below said shoulder.- The object in having the packing ring 15 extend downwardly below the lower edge of its recess is to afford adequatev opportunity for, at the proper time, the compression in a vertical direction of said ring. I

Thesplit locking ring 20 is formed from a strip of sheet metal and comprises side walls 24, whose upper edges are deflected inwardly, as at 25, a flange 26 extending inwardly from the lower edges of said side walls 24:, and a flange 27 extending downwardly from the inner edges of said flange 26, and the said lockingring isso'proportioned to the cap 18that when in position thereon the flange 26. will engage the lower surface of the packing ring 19 and the side I walls 24' will encompass the outer surfaces of the flange 23 of the cap, while the upper deflected portion 25 of the locking ring converges inwardly over the flange 22 of said cap. The locking ring 16 being a split ring may be applied laterally over the flanges 22, 23 of the cap or upwardlyover the lower end of'the cap.

the deflected flange portion 25 with a tongue.

29 adapted to the size of the said recess 28. Inwardly from the tongue 29 the locking ring 20 has anelongated recess 30 formed by removing a limited section of the flange portion 25 of the ring, and said recess 30 bemg about equal in length to the distance the recess 28 is set inwardly from its end of said ring, the purpose being in the final application of the locking ring. that the end 31 of the ring shall overlap the end 32 thereof,

that the tongue 29 shall be'pressed down- ,wardly upon the flange 22 of the cap, as

shown in Figs. 7 and 11, that that portion of the ring numbered 33 and extending from the recess 28 outwardly shall be pressed downwardly through the recess 30 of the other end of the ring and engage the upper surface of the flange 22 of the cap, as shown in Figs. 7 and 10, and that during the flattening of the flange-portion 25 ,of the ring the recess 28 thereof shall close down along the opposite edges of the tongue 29, as shown in Figs. 1 and The recess'28 extends outwardly slightly beyond the line' on which the upper flange 25 is bent inwardly so that said recess may close downwardly along the opposite edges of the tongue 29, and the edges of said rc cess, throughout their entire length, is brought into line with the entire length of the edges of said tongue,'whereby-.a very strong interlocking engagement of the ends of the ring is secured. The recess 30 extends outwardly to the line on which the upper flange 25 is bent inwardly so that said recess may receive the full width of that portion numbered 33 of said flange, as shown. When the ring is in its final position there is an interlocking engagement of its end portions throughout the entire width of the upper flanged portion 25 thereof, and this is important because thereby such engagement is effective to resist excessive internal pressure within the receptacle and the expansive force of the compressed packing 19 and the upper flanged portion 25 of the ring is left flat.

In applying the closure to the bottle-neck, the cap 18 and packing-ring 19 may be first passed downwardly upon the bottle-neck and the locking-ring 20 then positioned, or the cap, packing-ring and locking-ring may be assembled and applied to said neck. When the parts of the closure are in position on the bottle-neck, care will be taken to see that the ends of the locking-ring 20 overlap each other and that the tongue 29 and recess 30 of the inner end are respectively in alinement with the recess 28 and portion 33 of the outer end of said ring. After the closure has been applied to the bottleneck, the upwardly and inwardly deflected portion 25 (including the tongue 29 and portion 33) and the flange 26' of the locking-rin will be subjected to pressure in a vertical irection, tending to force said members 25, 26 toward each other,-this pressure having the effect of forcing the flange 25 into firm contact with the flange 22 of the cap andthe flan e 26 against the lower surface of the pac ingring 19, the latter being thereby compressed as shown in Fig. 6 against the walls of the recess formed by the flan es 26, 23, 22 and against the exterior side 0 the bottle-neck, a portion of said packing-ring being squeezed lateral y from without said recess and below the shoulder on said neck, whereby said packing-rin is caused to securelv seal the bottle and said closure to become eifectually locked without the recess 28, tongue 29, recess 30.

in position. It will be observed on reference to Fig, 6 that the packing-ring due to the vertical compression has been reduced in vertlcal diameter and that a portion of said ring has been squeezed inwardly below the shoulder 17. 1

During the vertical compression of the u per and lower opposite portions of the lockmg ring agamst the annularly projecting port on of the cap and the packing-ring, the portion 33 at one end of the locking-ring becomes laid within the recess 30 in the opposite end portion thereof and the recess 28 becomes horizontal and incloses at its opposite edges the then horizontal or flattened tongue 29, the whole ,bein left in. the condition shown 1n Figs. 1 an 7. The locking-ring 20 and portion 33, is shown in my aforesaid Letters Patent No. 795,283 granted July 25, 1905, and the present invention is designed as an improvement upon the construction shown in my said patent: The structure shown in my aforesaid Letters Patent is entirely eflicient for all usual conditions, but if have found that there are occasions in which highly excessive internal pressure seems to be generated within a sealed receptacle and that this pressure exerts a force tending to expand the locking-ring, and my present invention is to provide means for overcoming this result. I therefore make the locking ring sufliciently long to overlap at its ends and provide one end of said ring with the recess 30 set inwardly from its end of the ring and the other end of the ring with the inwardly set recess 28, so that after the final application of the closure to the bottle or receptacle any internal pressure tending to expand the ring will be resisted by the engagement of the edge of the recess 28 against the edge of the tongue 29, said tongue 29 at one end of the ring and the portion 33 at the other end thereof being flat and on the same horizontal plane when the parts are in final position.

When it is desired to remove the closure from the bottle-neck a sharp instrument may be inserted beneath the outer end of the spl1t ring and said end pressed outwardly from -wardly and-the recess 30 extended that part'of the other end of the ring which it overlaps, this resulting in the portion 33 of the outer end ofthe ring being forced outwardly from the tongue 29, and the said outer end of the ring having thus been started outwardly it may be taken hold of and the ring stripped from the flanges 22, 23 of the cap, the latter being thus left free to be lifted from the bottle-neck.

What I claim as my invention and desire to secure by Letters Patent, is:

In combination with a bottle or other receptacle, a closure therefor comprising a cap having side walls whose lower edges are flanged outwardly and downwardly forming a recess, a packing-ring in said recess and initially extending downwardly below the same, and a split locking-ring'applied upon the flanged portion of said cap and engaging the upper surface thereof and the lower surface of said packing-ring, said locking-ring being reduced in vertical diameter against the flanged portion of said cap and said packingring and ,with said flan ed portion holding a peripheral portion 0% said packing-ring squeezed from said recess against said receptacle, said locking-rin having overlapping end portions, one of w ich in its upper edge is formed inwardly from its end with a recess (28) .and the other of which is formed in its upper edge with a tongue (29) adapted to said recess and a recess (30) adapted to receive that portion of the upper edge of the ring between said recess 28 and the adjacent end of the ring, and said tongue and said recesses being of substantial length, with the recess 28 extending outwardly slightly be- I yond the line on which the upper flange (25) of said ring is bent outwardly to said bending line; substantially as set forth.
